Uric acid is the end product of purine metabolism and is mainly produced by the enzymatic breakdown of nucleic acids and other purine analogues from cellular metabolism as well as purines from food. Therefore, a low purine diet is a dietary principle that should be strictly observed by patients with hyperuricemia. All foods with low purine content can be consumed, such as most vegetables, fruits, dairy products, rice and noodles, which have low purine content and are suitable for daily consumption. However, high purine diet should be avoided, such as seafood, animal offal, beans, mushrooms, thick meat soup, beer, white wine, yellow wine, etc. Moreover, since patients with hyperuricemia are prone to combine chronic diseases such as fatty liver and diabetes, their daily diet should be adjusted scientifically and reasonably according to their weight, blood lipids and blood sugar level in addition to adhering to the principle of low purine. For example, for patients with combined diabetes, in addition to a low purine diet, the intake of staple foods such as rice and noodles should not be excessive; and for patients with combined hyperlipidemia, in addition to a low purine diet, the intake of fatty foods should not be excessive. Soybean milk is made of beans, soybean is high purine food, gout guidelines are not recommended, but the processed products of beans are tofu, soybean milk, after processing purine value is reduced, in fact, there are 166.5mg purine per 100g soybean, calculated by adding water to grind into soybean milk, only 10.4mg purine per 100g soybean milk, and the purine amount is less than 25mg purine content belongs to the low purine group, so soybean milk It is a low purine food, therefore, it is still okay to drink a cup occasionally, but it is not recommended to consume it frequently. In conclusion, patients with hyperuricemia should always strictly adhere to the dietary principle of low purine diet and avoid the intake of high purine diet, because beans are rich in purines, so patients with high uric acid should not drink too much soy milk.
